From Mindfulness To Buddhahood

Constantly giving rise to good faith in the Great Vehicle
[for delivering one and all to Buddhahood],
personally know that I am [you are]
a yet to be accomplished Buddha,
that all Buddhas are already accomplished Buddhas,
and give rise to Bodhicitta [the aspiration for Buddhahood], with every thought never away from this aspiration.

– Sakyamuni Buddha (Brahma Net Sutra)

念念心念佛, 念念心成佛。

With thought to thought,
the mind being mindful of a Buddha,
with thought to thought,
the mind [eventually] becomes a Buddha.

– Stonepeace

诸佛如来是法界身， 入一切众生心想中。 是故汝等心想佛时， 是心即是三十二相，八十随形好。 是心作佛，是心是佛。 诸佛正遍知海，从心想生。

– 释迦牟尼佛 (观无量寿佛经)

All Buddha Tathagatas are the Dharma realm’s body,
who enter all sentient beings’ minds’ thoughts within.
This is as when the minds of yours and others think of [a] Buddha,
your minds are the 32 forms and their 80 accompanying excellences.It is the mind that becomes [a] Buddha, it is the mind that is [a] Buddha.
All Buddhas’ [immeasurably broad and deep]
ocean of perfect and complete awakening
from the mind’s thoughts arise.

– Sakyamuni Buddha (Sutra Of Contemplation Of The Buddha Of Immeasurable Life)
